| 摘要: |
| 根据汉坪咀混凝土面板堆石坝的工程设计，用弹塑性平面有限元法，计算了堆石坝坝体、防渗体系的应力和变形．据此，对整个坝体的施工程序、趾板(包括连接板)的长度和防渗墙的刚度进行了分析比较．综合考虑各因素后，建议了适宜的堆石坝防渗体系设计方案． |

| Abstract: |
| Based on the design of Hanpingzui rockfill dam with concrete facing slab, the stresses and deformations of the dam body and impervious system are calculated by using the elastoplastic plane finite element method. According to the calculation results, the influences of the construction operation program, the length of the toe slab (connecting slab) and the rigidity of the diaphragm wall are compared. A rational design scheme for the impervious system of the rockfill dam is suggested after comprehensive analyses of all the influence factors. |
